Nightmare tried with all his strengh to fight the Shredder ... but Shredders power was growing and after a fight Nightmare was seriusly injured. For himit was now uselessto fight and he was hopeless.... they hunt him and as good as he can he tried to hide....but they found him again he tried to fight but he was too weak and his last hope and power was gone... they were about to kill him but then Shredder made him an offer ... he would heal him, gave him alot of power if he fight on his side and obey him without hesitation..... the reason why he gave up and joined the Shredder....Now he is a killer... a assassin who hunts everyone who is fighting against his master..... especially the turtle brothers......

Silent- you...you sided with them...my feelings for you are gone and will never be again! I will kill you for siding with the enemy! * launches forward her broken eyes screaming "help me" as rage burned through her*

Silent- *teleports to a stopping motion and whoops her head around* does it look like I care *a voice that want the one nightmare remembered spoke through her throat* even if you were being forced too I would still kill you! *launches forward this time her claws ready to kill*

Fine.... *he scowled slightly and a silent snarl Sounds through his slightly barred teeth*...if you want to kill me... i wont have a problem to take you down and rip your head off!....*his hand rested on his sword and he twirled the chain*

Silent- *grins her voice still unfamiliar to nightmare* good then I can kill you and her at the same time! *she widens her eyes noticing her slip up* that is if you haven't already noticed the difference in your FORMER ally Silentnight.
